RE: DRAW LENGTH QUESTION
You may have to change it a little because the string angle may change switching to the release. The way you anchor to your face will change for sure. It will move farther back on your face, like below your ear, or behind hour jaw bone. It will take some getting used to for sure. Go to a shop and play with different draw lengths and the such to see what is the most comfortable to you when you shoot. Maybe it isn't the best it could be right now? Most people shoot too long a draw length to begin with.
